wots wrong with my biasi boiler m96.28sm/b2, it will come on for a few minutes but will then go off. It's just over 12 months old it was working fine untill about a week ago then it just stoped. There are 4 lights on the front of it that should be all green but only 2 of them are and the other 2 are red. How do i sort this problem out with out it costing me a lot of money?
